Fluorescence Properties and Mg2+ Selectivity of Aryl‐Alkynyl Derivatives of the o‐Aminophenoltriacetate (APTRA) Ligand

Chemistry – A European Journal, EarlyView.
It is a challenge to improve the selectivity of high‐denticity ligands for Mg2+ over Ca2+. We show that in aryl‐alkynyl derivatives of APTRA, electron‐withdrawing substituents lower the binding affinity for Ca2+ more than Mg2+, making the ligand more selective for Mg2+.

Silent Partners in the Mill: Unveiling the Role of Additives in Mechanochemical Synthesis

Chemistry – A European Journal, EarlyView.
Mechanochemistry offers a sustainable, solvent‐free alternative to traditional synthesis, often enhanced by additives in a process known as additive‐assisted grinding. This review discusses how various additives, including liquids, ionic solids, and advanced materials like ionic liquids and piezoelectric compounds, improve reaction efficiency ...

Development of a Highly Sensitive Time‐Resolved Fluorescence Immunochromatographic Assay for Rapid Onsite Determination of Prometryn Residues in Food Samples

Food Safety and Health, EarlyView.
The recombinant full‐length antibody against prometryn (PRO‐rAb) was prepared by HEK293 (F) cell expression system and utilized as the foundation for time‐resolved fluorescence immunochromatographic assay (TRFICA). The established method showed good performance for the detection of prometryn residues in five food samples. ABSTRACT Prometryn, a triazine
